Abstract
A chemosensor (CS) was designed and synthesized by simple method. Dual-channel instant detection of CN− was achieved under acidic conditions. It showed an immediate visible color change from yellow to colorless and blue fluorescence appearance when CN− was added. Colorimetric and fluorometric methods showed the detection limits of CN− were 3.9×10−8 and 3.1×10−9 M, respectively. The mechanism of chemosensor reactions with CN− ion was examined using 1H NMR spectroscopy, FTIR spectroscopy, and DFT calculations. Test strips, which served as convenient and efficient CN− test kits, were fabricated based on the sensor.
